Excitation function of nucleon and pion elliptic flow in relativistic heavy-ion collisions
Within a relativistic transport (ART) model for heavy-ion collisions, we show that the recently observed characteristic change from out-of-plane to in-plane elliptic flow of protons in mid-central Au+Au collisions as the incident energy increases is consistent with the calculated results using a stiff nuclear equation of state (K= 380 MeV). We have also studied the elliptical flow of pions and ...
متن کاملPion flow and antiflow in relativistic heavy-ion collisions.
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies, we study the transverse flow of pions with respect to that of nucleons using two complementary approaches. It is found that in central collisions pions develop a weak flow as a result of the flow of baryon resonances from which they are produced. On the other hand, they have a weak antiflo...
متن کاملElliptic flow of deuterons in relativistic heavy-ion collisions
Using a dynamical model based on the NN → dπ,NNN → dN , and NNπ → dπ reactions and measured proton and pion transverse momentum spectra and elliptic flows, we study the production of deuterons and their elliptic flow in heavy-ion collisions at RHIC. The results are compared with those from the coalescence model. The deviation of deuteron elliptic flow from the constituent nucleon number scaling...
متن کاملKaon and Pion production in relativistic heavy-ion collisions
The BUU transport model is applied to study strangeness and pion production in nucleus-nucleus collisions. Starting from proton induced reactions, we further investigate Si+Au, Au+Au and Pb+Pb collisions in the energy range between 2 and 40 A·GeV and compare with data and with other transport calculations. The qq̄ annihilation, or resonance, channel simulated by the string model in meson-nucleon...
متن کاملPion ow and anti ow in relativistic heavy-ion collisions
Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies, we study the transverse ow of pions with respect to that of nucleons using two complementary approaches. It is found that in central collisions pions develop a weak ow as a result of the ow of baryon resonances from which they are produced. On the other hand, they have a weak anti ow in pe...
